Genetics Home Reference:22 Succinic semialdehyde dehydrogenase deficiency is a disorder that can cause a variety of neurological problems. People with this condition typically have developmental delay, especially involving speech development; intellectual disability; and decreased muscle tone (hypotonia) soon after birth. About half of those affected experience seizures, difficulty coordinating movements (ataxia), decreased reflexes (hyporeflexia), and behavioral problems. The most common behavioral problems associated with this condition are sleep disturbances, hyperactivity, difficulty maintaining attention, and anxiety. Less frequently, affected individuals may have increased aggression, hallucinations, obsessive-compulsive disorder (OCD), and self-injurious behavior, including biting and head banging. People with this condition can also have problems controlling eye movements. Less common features of succinic semialdehyde dehydrogenase deficiency include uncontrollable movements of the limbs (choreoathetosis), involuntary tensing of the muscles (dystonia), muscle twitches (myoclonus), and a progressive worsening of ataxia.

MalaCards: Succinic Semialdehyde Dehydrogenase Deficiency, also known as 4-hydroxybutyric aciduria, is related to wagr syndrome and juvenile absence epilepsy, and has symptoms including organic acid metabolism anomalies, psychic/behavioural troubles and hypotonia. An important gene associated with Succinic Semialdehyde Dehydrogenase Deficiency is ALDH5A1 (aldehyde dehydrogenase 5 family, member A1), and among its related pathways are Arginine and proline metabolism and Neurotransmitter Release Cycle. The compounds Succinic acid semialdehyde and vigabatrin have been mentioned in the context of this disorder. Affiliated tissues include globus pallidus, brain and liver.

Disease Ontology:9 A gamma-amino butyric acid metabolism disorder that is characterized by a deficiency of succinic semialdehyde dehydrogenase resulting in elevated levels of gamma-hydroxybutyric acid.

NIH Rare Diseases:44 Succinic semialdehyde dehydrogenase (ssadh) deficiency is disorder that can cause a variety of neurological and neuromuscular problems. the signs and symptoms can be extremely variable among affected individuals and may include mild to severe intellectual disability; developmental delay (especially involving speech); hypotonia; difficulty coordinating movements (ataxia); and/or seizures. some affected individuals may also have decreased reflexes (hyporeflexia); nystagmus; hyperactivity; and/or behavioral problems. ssadh deficiency is caused by mutations in the aldh5a1 gene and is inherited in an autosomal recessive manner. management is generally symptomatic and typically focuses on treating seizures and neurobehavioral issues. last updated: 9/25/2013
